Overview
At Blackstone Valley Consulting, I learned and configured the SAP Forecast to Stock module and led the migration of Functional Locations, Equipment, and BOM data off a legacy system (MYOB) into SAP — coordinating with teams in the US and Australia to keep the acquisition's operations running through the cutover.
Alongside the migration, I built middleware integrating SAP iDocs and carrier data, moving legacy SAP workloads from on-prem infrastructure to Google Cloud, and hosted Vertex AI agents that aggregate customer support tickets from separate services into a single internal dashboard.
Highlights
- Migrated Functional Locations, Equipment, and BOM data with virtually no downtime during a critical legacy system cutover.
- Built SAP iDocs/carrier middleware and moved it from local infrastructure to Google Cloud.
- Hosted Vertex AI agents to aggregate and triage customer tickets into one dashboard.
